The largest animals are marine filter feeders, but the underlying mechanism of their large
size remains unexplained. We measured feeding performance and prey quality to …

Among anthropogenic activities, marine seismic surveys are a fundamental tool for oil and
gas explorations, geophysical research, environmental hazard, and risk analysis. This …

The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in
Europe. There are particular concerns about this species in the Baltic Proper, Black, and …

Reliable estimates of field metabolic rates (FMRs) in wild animals are essential for
quantifying their ecological roles, as well as for evaluating fitness consequences of …

In marine environments, noise from human activities is increasing dramatically, causing
animals to alter their behavior and forage less efficiently. These alterations incur energetic …

Knowing the abundance of a population is a crucial component to assess its conservation
status and develop effective conservation plans. For most cetaceans, abundance estimation …

Harbour porpoises Phocoena phocoena are common in continental shelf areas of the North
Atlantic, but little information is available on their occurrence outside coastal areas. In this …

The North Sea is one of the most heavily used shelf regions worldwide with a diversity of
human impacts, including shipping, pollution, fisheries, and offshore constructions. These …

Harbour porpoises are visually inconspicuous but highly soniferous echolocating marine
predators that are regularly studied using passive acoustic monitoring (PAM). PAM can …

Research has shown that noise disturbance can disrupt the behavior of harbor porpoises.
The significance of such disturbance is unclear. However, these animals may be vulnerable …
